HEAT ANTICIPATOR SETTINGS

Set heat anticipator settings at 0.14 amp for the first stage and
0.14 amp for second-stage heating, when available.
Electric Heaters
50LC units may be equipped with factory or field-installed
electric heaters. The heaters are modular in design, with heater
frames holding open coil resistance wires strung through ce-
ramic insulators, line-break limit switches and a control con-
tactor. One or two heater modules may be used in a unit.
Heater modules are installed in the compartment below the in-
door (supply) fan outlet. Access is through the indoor access
panel. Heater modules slide into the compartment on tracks
along the bottom of the heater opening. See Fig. 36 - 38.
Not all available heater modules may be used in every unit.
Use only those heater modules that are UL/ETL listed for use
in a specific size unit. Refer to the label on the unit cabinet for
the list of approved heaters.
Unit heaters are marked with heater model numbers. However,
heaters are ordered as and shipped in cartons marked with a
corresponding heater sales package part number. See Table 3
for correlation between heater model number and sales pack-
age part number.
NOTE: The value in position 9 of the part number differs between
the sales package part number (value is 1) and a bare heater model
number (value is 0).
